DUAL TEMPERATURE REFRIGERATION CIRCUIT

摘要

Combined medium and low temperature refrigeration circuit (2) for circulating a refrigerant in a predetermined flow direction, comprising in flow direction (a) a heat-rejecting heat exchanger (4); (b) a medium temperature refrigeration consumer (6); (c) a medium pressure vapor separator (8) having a vapor portion (36) and a liquid portion (38) connected to the medium temperature refrigeration consumer unit; (d) a low temperature refrigeration consumer (14) connected to the liquid portion (38) of the medium pressure vapor separator (8); and (e) a compressor unit (16) having an inlet () connected to the vapor portion (36) of the medium pressure vapor separator (8) and the low temperature refrigeration consumer (14).
